Application aledamie ze, 1920. serial No. 391,881.

To all fw hom it may concern Be it known that I, JOHN H. Srnorrr, acitizen of the United States, residing at Cleveland, in the county ofCuyahoga and State of Ohio, have invented a certain new and usefulImprovement in Friction-Top Cans, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings.

rThis invention relatesto cans andinore particularly to Cans of the typeemploying a detachable friction top for closing the head thereof.

Some of the objects of the present invention are to provide a can thecover of which is so formed as to provide an air space above thecontents of the can when the cover is applied to the receiving portionthereof; to provide a can the receiving portion of which shall be soformed as to present a reinforcing rib which shall prevent distortionthere of even though the can is opened and closed repeatedly; to providea can which shall present a flat surface when the cover is applied andthereby permit convenient stacking of such cans; also to provide a canwhich shall be simple in construction and inexpensive of manufacture.Further objects and advantages will appear as the description proceeds.

In the accompanying drawings wherein l have shown an illustrativeembodiment of my invention, but without intent to limit myself thereto,Fig. 1 is a view, partly in section, of a portionV of my improved canwith the cover detached; Fig. 2 is a vertical sectional view of aportion of my improved can with the cover applied thereto; and Fig. 3 isan enlarged detail sectional view showing the cover applied to thereceiving portion of the can.

Describing the various parts by reference characters, 1 indicates areceiving ring fastened to the upper edge of the can body 2 in anyapproved manner, as by the double seam indicated at Si. On its innerside, the receiving ring 1 is bent inwardly as indicated at 1 and thenupwardly, as shown at 5, to form a strengthening rib. The main frictionseat for the cover is formed by continuing the bend 5 downwardly atsubstantially right angles to the body of the ring, to form a verticalwall, as indicated at 6. The metal is then curved upwardly to form asemi-circular seat and strengthening rib 7,

the latter preventing the wall 6 from becoming distorted by theapplication and removal of the cover.

The cover S is formed with a lateral flange 9 which has its outeredgeturned under, as indicated 10, to form a finished surface therefor andto receive therebeneath the article by which the cover will be removed.The inner portion of the flange is turned. upwardly-at 11 to conform tothe rib 5 yand then downwardly at substantially right angles thereto, toform a vert-ical wall 12, and is then shaped to provide a semi-circularrib 13, the parts 12 and 13 being adapted to contact respectively withthe wall 6 and the seat 7, to form a continuous tight joint therewith.The semi-circular rib 13 is continued upwardly and inwardly, as shown at1&1, to the central portion 15 of the cover, which portion lies in aplane with the rib 11 and t-he top of the double seam 3 and thus formsan air spiace between the inner end of the rib 7 and cover 8. It isapparent that an expansion chamber is thus provided above the combinedrib and seat 7 which is advantageous for applying the cover as well asin the event that the can is used for easily volatilized substances. Itis also apn parent that have provided a can the cover of which is fiatacross the top surface thereof, permitting easy stacking of a number ofcans on a shelf, one above the other. Furthermore, the manner of formingthe parts 12, 12S and 4.11 prevents distortion of the seating portion ofthe cover and adds to the strength thereof. r1`he arrangement of thedouble seam 3 and the rounded or wire edge 10 of the cover enables asuitable tool or article to be conveniently inserted beneath such edge,the double seam furnishing a fulcrum by means of which the Cover may bereadily removed. Furthermore, should any of the liquid contents of thecan escape over the rib 7, practically all such liquid will flow backinto the can.

Having thus described my invention, what I claim is:

1. A friction top can comprising a body portion and a receiving portionsecured thereto and provided within its marginal portion with anupwardly projecting annular rib, with a vertical wall depending fromsaid rib and a concave inwardly projecting rib at the lower end of saidwall,
